Yes, and that is why many people have, at least historically, picked Python for their project. An interpreted language with a clean syntax and an avoidance of TIM-TOWTDI results not only in a Rapid Development, but also less headaches during the maintenance lifetime of the software. But we cannot _always_ know what the final destination of our software may be. Many times a simple project can grow into an enormous beast, and by the time we realize that Python is too slow, we're faced with only bad choices and worse choices. > if this were not the case then we would all be writing > Assembler Only a few, poor, masochistic souls choose to write assembly, the rest of us try to avoid pain as much as we can. ;-) -- https://mail.python.org/mailman/listinfo/python-list
